  1. 1. Glass-forming ternary blends: towards stable Polymer Solar Cells

    Författare :Amaia Diaz de Zerio Mendaza; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; organic photovoltaics; glass formation.; fullerenes; ternary blends; thermal stability;

    Sammanfattning : The globally increasing use of electricity goes hand in hand with climate change and the gradual depletion of fossil sources of fuel. To address these challenges renewable sources of energy are in high demand. LÄS MER

  3. 2. Drying of Multicomponent Liquid Films

    Författare :Fabio Luna; KTH; []
    Nyckelord :ternary mixture; falling film; diffusion equation; gas-phase control; liquid-phase control; selectivity; stability analysis; polymeric solution; evaporation; azeotrope; batch drying; continuous drying;

    Sammanfattning : The convective drying of thin layers of multicomponentliquid mixtures into an inert gas, and the influence ofdifferent process controlling mechanisms on drying selectivityis studied. Drying experiments under gas-phase-controlledconditions are performed by low intensity evaporation, fromfree liquid surfaces, of ternary mixtures without non-volatilesolutes. LÄS MER

  4. 3. An Analytical Solution Applied to Heat and Mass Transfer in a Vibrated Fluidised Bed Dryer

    Författare :Apolinar Picado; Joaquín Martínez; Göran Lindbergh; Ivars Neretnieks; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Analytical solution; Heat and mass transfer; Temperature and moisture distribution; Drying modelling; Multicomponent drying; Drying selectivity; Volatile retention; Ternary mixture; Drying of particulate materials; Vibrated fluidised bed dryer; Chemical engineering; Kemiteknik;

    Sammanfattning : A mathematical model for the drying of particulate solids in a continuous vibrated fluidised bed dryer was developed and applied to the drying of grain wetted with a single liquid and porous particles containing multicomponent liquid mixtures. Simple equipment and material models were applied to describe the process. LÄS MER

  5. 4. Transport Coefficients during Drying of Solids containing Multicomponent Mixtures

    Författare :Rafael Gamero; Joaquín Martínez; Evangelos Tsotsas; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; capillary; conduction; convection; diffusion; evaporation; heat transfer; hydraulic conductivity; liquid film; liquid transport; mass transfer; Maxwell-Stefan diffusion coefficients; molar fluxes; phase equilibrium; temperature gradient; ternary mixture; thermodynamic factors; Chemical engineering; Kemiteknik;

    Sammanfattning : This study investigated the transport coefficients involved in mass and heat transfer during the drying of a porous solid partially saturated with multicomponent mixtures.  It included the coefficients governing liquid transport through the solid, the matrix of multicomponent diffusion coefficients in the liquid phase, and the effective thermal conductivity.

  7. 5. Synthesis and Characterization of Ternary Carbide Thin Films

    Författare :Ola Wilhelmsson; Ulf Jansson; Michael Stueber; Uppsala universitet; []
    Nyckelord :Chemistry; Thin film; dc magnetron sputtering; tribology; carbide; PVD; MAX-phase; DFT; solid solution; Kemi;

    Sammanfattning : This thesis reports on synthesis, microstructure and properties of binary and ternary carbide thin films deposited by dc magnetron sputtering. These materials are interesting since they exhibit a wide range of useful properties, such as high hardness, resistance to wear and oxidation, and high electrical conductivity. LÄS MER
